I'd say at the very least, tyre wise you'd be looking at a 235-35-19 possibly even having to go to a 30 profile, and they ain't gonna be cheap. And with the lowering aswell its gonna be quite a bumpy ride (mainly because of the tyres) the springs you mention come in a 'comfort' form also. Which are a little softer than conventional lowering springs.

Thanks for your response Mike,Would the comfort form of the springs still lower the car and how do i tell the difference between the standard lower and comfort lower, is the comfort lower ones black and the standard lower ones blue?

Also i travel mostly on motorway or around town, i dont have many speed ramps or pot holes,Would the ride still be hard?This is my first time lowering a car, and id bare the cost of the rubber they should last me two years.Maybe pay for the tyres with the sale of my existing 16" snow flakes with tyres and centre caps.

Just make sure you have a dentist 30mm eibachs were blue no idea what black ones are with those tyres at such a low profile and tge springs yep it will be a bumpy ride

Thanks Im starting to get the picture lolOk if i leave the existing springs in place,Then replace the 16" alloys with 19" then that would do the job of filling the arches right?And maximise the amount of space left for a tyre wall?

If you fit 19's without lowering it, its more than likely gonna look like its on stilts, or a giant roller boot lol. Whichever route you take it is going to be a firmer ride. The comfort springs are a lowering spring, just a bit softer over the bumps, but still uprated from the standard ones. The tyres will be the biggest factor in making for a bumpy ride, and you can't make up the gap from not lowering it with a bigger side wall, the rolling circumference of the old wheels and the new ones should be as close as possible, hence why you would be going from say a 55 profile, to a 35 ish. So the wheels would be bigger but the lower profile tyre would make them roughly the same size as your old ones if stood side by side...

Ford eibachs are 30mm from what I saw when I fitted them to my old st, you will need a 235/30r19 tyre which will be the best option as there only -1.5% difference where as a 35 profile is nearly +2.5% difference which is to much.

Oh yeah it's gonna be hard either way, I had a Mondeo st200 and I first put full spax adjustables on it set to full hardness with the stock 17s but when I went to 18s with 2254018 it nearly broke my back had to adjust them to full soft to make it comfy again.

doing some research... you could use 225/30r19's on an 8 Inch Rim... this would give you a 0.47% change... or 3mm diameter lol

Worth checking with a tyre garage though... From what i could find ideal tyre width for an 8.0 is 225/235, minimum being 215, max being 245...

would be an incredibly harsh ride though... especially on the roads in this country!!! you may as well fit elastic bands to the rims

A 225/30r19 would be very uncomfortable and look to thin on the car, 235/30r19 is the way to go for having a bit of comfort still.

as much comfort as a 30 profile can give lol

either way, bet its still bumpy

Thanks for all the information guys,Think ill look out for the comfort lower eibah springs and settle for the 18" rims instead of the 19"s Wouldnt be so bad if it was just me driving around but ill have two kids in the back some of the time so aint worth the hard ride.The quote elastic bands on the rims spelt it rite out for me lmao18's should be better though shouldnt they?And 40mm lowering springs...does this mean it lowers the car by 40mm or does it mean the car will be 40mm ground clearance when fitted.

Lowers the car body towards the wheels, not ground clearance. You'll prob find it drops by a bit more than 40mm in real life terms, once they have been on a few days and settled, you'll be pleased with the way it looks.

Cool thanks,Should be a good compramise then 18" rims with 40mm comfort springs.
